If the YASKAWA Controller does not allow you to select the desired Auto-Tuning mode, it is because the desired Auto-Tuning mode is not available for the selected control mode. Check if the desired tuning mode is available for the selected control mode and change the motor control method by setting A1-02.
What to do if my YASKAWA Inverter Drive continues to operate after an EF0 fault?
If your YASKAWA Inverter Drive continues to operate when an EF0 fault is detected (when set to 3), take proper safety measures. For example, install an emergency stop switch.
Why can't I change parameter settings on my YASKAWA L1000A?
There are several reasons why you might not be able to change parameter settings on your YASKAWA Controller: * The drive may be running the motor. Stop the drive and switch to Programming Mode, as most parameters cannot be edited during run. * The Access Level might be restricting access. Change the Access Level to allow editing (A1-01 = 2). * You may not be in Parameter Setup Mode. Verify the digital operator mode and switch to Programming Mode. * An incorrect password may have been entered. Reset the password by scrolling to A1-04, pressing STOP and simultaneously. Parameter A1-05 will appear, allowing you to set a new password. * Undervoltage may have been detected. Check the drive's main input voltage via the DC bus voltage (U1-07) and inspect all main circuit wiring.
Why is my YASKAWA L1000A motor too hot?
If the load is too heavy for the motor, it may overheat because it exceeds its rated torque value for an extended period. Consider that the motor has a short-term overload rating. You can: 1. Reduce the load. 2. Lower the acceleration and deceleration ramps by increasing the acceleration and deceleration time. 3. Check the values set for the motor protection (L1-01, L1-02) and the motor rated current (E2-01). 4. Increase motor capacity.
How to reduce electrical noise from YASKAWA L1000A Controller?
Electrical noise from the YASKAWA Controller or output lines during operation can be due to excessive PWM switching noise. Try these solutions: * Lower the carrier frequency (C6-03). * Install a noise filter on the input side of the drive input power. * Install a noise filter on the output side of the drive. * Place the wiring inside a metal conduit to shield it from switching noise. * Ground the drive and motor properly. * Separate the main circuit wiring and the control lines. * Ensure wires and the motor have been properly grounded.
What to do if YASKAWA L1000A motor rotates in opposite direction?
If the YASKAWA Controller motor rotates in the opposite direction from the Up/Down command, it could be due to: * Incorrect phase wiring between the drive and motor. Check the motor wiring. * Drive control circuit terminals for the Up and Down commands are switched. Check the control circuit wiring and correct any fault wiring.
How to unlock parameter settings on YASKAWA Controller?
If the YASKAWA Controller does not allow changing parameter settings, it might be due to: * The drive is running the motor. Stop the drive and switch to the Programming Mode, as most parameters cannot be edited during run. * The Access Level is set to restrict access. Change the Access Level to allow parameters to be edited (A1-01 = 2). * The operator is not in the Parameter Setup Mode. Switch to the Programming Mode. * The wrong password was entered. Reset the password. If the password is unknown, scroll to A1-04, press STOP and press at the same time. Parameter A1-05 will appear and set a new password to parameter A1-05. * Undervoltage was detected. Check the drive main input voltage by looking at the DC bus voltage (U1-07) and check all main circuit wiring.
What does encoder offset error mean on YASKAWA L1000A?
If the encoder offset (E5-11) set during Auto-Tuning (Rotational or Stationary) consistently differs by 30 degrees or more on your YASKAWA Controller, it indicates that the PG-E3 option detected excess position error with the ERN1387 encoder. Perform Auto-Tuning of PG-E3 encoder characteristics (T2-01 = 12).
